Sennheiser HD 600

I love these, a lot. From the way they look to every detail of their sound, they're truly beautiful. They have sliky smooth, characteristic treble that doesn't fatigue your ears one bit even at high volumes, and I say this as someone who *really* likes treble. Their mids are beautifully balanced and neutral, the bass (well, what's there of it) is defined and not muddy in the least, they sound incredibly clean, precise and pleasant.

However, there are some issues:

The sub-bass is quite disappointing. To the point I might actually recommend against these if you are going to listen to bass-heavy music like EDM. There is just hardly any real deep body to the sound, it feels a bit shallow and empty. This works *amazingly* for genres like classical or acoustic stuff, and I would never want other headphones than these for those genres, they're beautiful for that. However, I did find myself using a corrective EQ setting to boost the bass a little bit, just to make it go along a bit better with some of the genres I listen to.

Also, the soundstage isn't that great. I've used much cheaper in-ear monitors that have better soundstages, it really doesnt sound all that wide or free or spacious. It's still pleasant and doesn't feel boxed in, but it is something I would expect to be better in headphones at this price range.

All in all, I love these, and would recommend these to most people. They're great as reference headphones, they work well for music production and I feel like they're something you won't regret having around, as they have very clear strengths that I feel are very hard to rival in this price range. However, they do lack in some aspects, so maybe relying entirely on these if you listen to bass-heavy music, for example, might not be your best bet, unless you're willing to help out with corrective EQ.

I have had about five AKG k702 headphone before I made the decision to buy the Sennheiser HD600, and I have had it on my radar for a long time,
I like the speckled version better from the 90's it is imo such a shame they changed that, but....it has nothing to do with the first impressions and experience I have with the HD600.
Compared to the K702 which is a cheaper, I was suprised that the wires for both ears are kind of close together when you put the HD600 on...
I did not like that at all and the fact that the wire is not tangle free is a second that will come due time and it will bother me just thinking about
it.. The AKG K702 has a wire to one ear and a tangle free 3m wire which is comfortable in that regard I like it more,
sound wise the AKG K702 is more open too and the mids are better, like mixing on NS10's , but the Sennheiser HD600 is fuller or better said has more low mids it seems but nearrow in stereo image, the reason why people like this headhone is probably because of this, low mid are renowed to hug your eardrum, they are the frequencies that make people say it sounds ''warm'' or ''full'' and they do, so this HD600 i will
keep to refference mixes and have an additional means to check my mixes. But to be clear, my main headphone will stay the AKG k702's for they sound more spacious and defined to me.
